Product Description
Proteinase K is a serine protease with wide cleavage activity, which can cleave the carboxyl-terminal peptide bond of aliphatic and aromatic amino acids. Its relative molecular weight is about 29.3 kDa. Proteinase K is widely used in the preparation of chromosomal DNA for pulse electrophoresis, Western blotting, and the removal of a nuclease from DNA and RNA preparation. Denaturant such as SDS (1%) can improve its activity. In addition, the common working concentration is 50-100 μg/mL, and the specific working concentration is according to whether the buffer contains SDS, urea, pH, temperature, and other factors.
Applications
- Genomic DNA extraction
- Digestion and removal of the enzyme
Features
- Derived from a genetically engineered yeast strain.
- Free of RNase and DNase contamination.
- Maintains stable activity in the presence of urea and SDS.
- Active across a broad pH range (pH 4.0 – 12.0), with optimal activity between pH 7.5 and 9.0.
